To (ZZZ whom it may concern:

Be it known that I, SAMUEL LIiesIUs, a

citizen of the United States, and residing at 105 John street, NewYork,"in the county of New York and State of New York, have Thisinvention deals with a unitary self-'- contained" apparatus in thenature of an embossographer', adapted automatically to produce,so-called raised, 'printing""' in simu lation of engraving. I

The primary object of this invention is to create and rendercommercially available an apparatus'which will enable printers toproduce imitation embossed Work so rapidly cheaply and easily as toenable large quantities of material to be turned out at a cost onlyslightly exceeding that of ordinary printing.

-' Heretofore, raised printing in imitation of embossed or engraved workhas been acmany disturbing influences and are quite incapable ofeffecting si'lbstantial economies in handling large orders, because ofthe fact that the expense cannot be materially reduced in proportion tothe volume of work features of construction, combinations of to beturned out. This invention, however,

by'reason of its automatic character and.

its nicety of control, enables the output to be greatly speeded upwhenhandling a large order of the same printedmatter, and consequentlythis invention further improves and the annexed drawings and in partindicated in connection therewith by-the following analysis of thisinvention.

This invention accordingly consists in the parts, and in the uniquerelations of the erence denote corresponding shown in sectionalelevation.

and disposition thereof; all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend theunderlying features thereof that they may embody the same by thenumerous modifications in structure and relation contemplated by thisinvention,

drawings depicting a preferred form have V been annexed as a part ofthis disclosure, and in such drawings, like characters ofrefpartsthroughout all the views of which Figure 1 is a side view of my combinedprinter, powderer, excess-remover, conveyer and fuser', parts; beingbroken away and i Fig. 2 is a vertical sectional elevation, drawn on anenlarged scale, of the powder-er for containing and distributing anexcess of the powder on theprinted portions of'a sheet. Fig.3 isacross-sectional view taken on the line 33 of Fig. 2. Fig. dis aperspective view illustrating one of the minor details of construction.Fig. 5 is aperspective view'of one form of sheet-feeder. Fig.6 is a'side view illustrating certain details of construetionthereof. Y I v Inthe accompanying drawings, I have shown how a printing press of theGordon variety may be embodied as one of the elements of my combination;enough onlyof the press and the other elemental mechanisms being shownto illustrate a fair example of a complete practical application of theinvention. In these drawings, 10 indicates the frame of the press; 12 isthe main driving-shaft: 13 is the prank-Wheel to which the pitman 15 isconnected by means of a wrist pin 14. This pitman 15 engages the shaft16 which is adapted to actuate the swinging-frame 17, and it extendstrans.

versely between the arms of the oscillating frame 22, which supports thetype. The

frame 17 ,is provided with an. offshoot 18 having a wrist-pin 19, towhich is connected alink 20. This link is pivoted to the frame 10,bymeans of the wrist-pin 21, and is I 23, having anaperture 24 forreeeiving bolts 25,, which are employed as a means for ad- .justablyconnecting the resilient arms 26 to the swinging frame; these arms, arerespectively provided with a slot 27,'Whereby they may be adjusted tosuit requirements.

Of the printed-sheet outwardly and away from it and its supporting quads32,-and

Each arm 26 is provided at its free end with a gripper A, comprising aresilient aw I '28 (see Fig. 5) having a stud 29, which passes throughan opening through the end of the resilient arm 26, wherebysaid aw isnormally-closed againstthe free end of said resilient arm. Pivotallyattached to the arm 26, by means of a pin 31, is a tapered gunle or pawl30, adapted for lifting the lower end guidingit between the-jaws of thegripper A. The platen 11 is provided with recesses 33 for accommodatingthefgrippers A, the surface of said recesses contacting with the studs29,,iasthe grippers enter for the purpose of' opening the jaws. 28,whereby the printed'sheet may readily enterthe grippers and be carriedaway thereby, as will be here-- inafter described:

. As a means for holding and distributing the powder, -I employ areceptacle B, em.

- ,bodying the upper compartment 35 and the lower compartment 39, theformer having outlet openings in its bottom which are normally closed bythe sliding door 36. This.

door is maintained in closed position by means of suitable springs 37.The sliding door 36-:moves on guides 38, and it is provided withdepending pins 36 for engagement with trips 34 projecting from theresilient arms 26. These trips open the sliding door during therearwardstroke of the arms 26, by means of their shoulders 1; their taperededgeparts 2 riding over said pins 36 on the forward stroke.

The compartment 39 is hopper-shaped and its outletleads .into a tube 41,which dis-- charges into the upper compartment 35. Said tube,immediately below the outlet of the hopper 39, is provided with aninjector nozzle 40 which leads from a suitable source printed sheets toshake the superfluouspowder therefrom.

Passing longitudinally between the upper and lower compartments 35 and39, areendless belts composed of flexible fabric, such as coarsewire-mesh, so that they need not lmpede'the powder from droppinginto thelower compartment 39. The belts 45 pass around rollers 46 and 47,.andthe conveying movement is imparted thereto by meansof a suitable sourceof power, such as a pulley 48 driven by means of a belt 49 which is, in

turn, driven from the main-driving shaft 12.

The roller .46 is journaled between suitable 76 uprights 50 mounted infixed relation to the main frame; and the roller 47 is journaled to the.main' frame 10. 'An offset constituting a trip 50 extends 'from asuitable support 52 and is adaptedto engage ,the' studs 29 ,ofthegrippers A to open the'jaws-28, at the end of the stroke of the swingingframe 17 whereby the sheet isreleased an allowed to drop on tothe-belts'45. I

As a meansfor heating the sheets to fuse the fusible powder into theink, an elongated bOX CI 1s em loyed This box'is'heated to the requiredegree by any suitable heating agent, and it has wire-mesh endlessbeltsI. 53 extended longitudinally "'therethrough for slowly carrying thesheets through the fusion zone of thebox. The sheets, as theyaredischarged from the belts 45, are fed on to the tilted table 54 andslide therefrom through an opening-55 into the heating receptacle C;within which they-are received by' thebelts53 and carried through thecompartment. Movement is transmitted to the belts 53by means of pulleys57, 58 and a belt 59. I have only shown one end of the heatingreceptacle,.as' I believethat to suflice for lllustrative purposes.

-During the operation of this invention," the compartment 35 will becharged with a,

suitable fusible powder and, as soon as a sheet 1s printed in aconventional manner, it

' is intermittentlygrasped at its lower edge by the grippers and carriedbeneath the compartment 35 of the powderer. Meanwhile, the powdererautomatically sprinkles powder on thesheet; this being done by the rear:

ward movement of the, resilient arms 26 which open the sliding door 36by means of their trips 34. The sheet thus receives an abundantor excesscoating of fusible pow- 'der on its printed surface. As soon as thesheet has been coated (and preferably just before itis released from thegrippers), the rotating shaft 43 comes into on the paper, whereby itspaddles 44 strike and agitate the,.sheet, thereby causing itssuperfluous powder to slide ofl' the non-tacky unprinted portions of thesheet and discharge into the lower compartment 39. The I 5 trip 51 thenopens the jaws 28 of the grippers. and allows the sheet to drop on tothe belts 45, from whence it is automatically fed to the heating andfusion chamber. During its passage therethrough, the fusible powder whchadheres to the tacky ink now melts effective action and amalgamateswith the ink, thereby pro- 'ducing raised printed matter.

The door 36- may be so timed in its movements as to either coat-theentire sheet or only parts thereof when it is desirable to produceprinted matterwhaving' parts 30m,-

posed of raised letters andi kparts: fiatembodying ordinary printing.All partsof the operation and improved'amethodiof production, however,require zthe employment of purely automatic mechanical means only,

, wherebythe process is-hastened, the'cost of production is {*lOWGIGCl,and. operatives "around thepress are shielded from the deleteriouseffects of the, powde1' andthe fumes engendered thereby;

*Without further analysis, the foregoing will so fully reveal the gistof-this invention that others can by applying current knowlconstituteessential characteristics of the "'genericor specific aspects'of thisinvention,

and therefore such adaptationsshould and are intendedto becomprehendedwithin the meaning and range of equivalency of the followingclaims.
